Self-Fluxing Copper/Phosphorus Brazing Alloys

FOS-FLO® alloys are copper based filler metals that are self-fluxing on copper by virtue of their phosphorous content. Because of their self-fluxing nature, you save time and money by eliminating the steps necessary to flux a joint before brazing. However, copper alloys such as brass and bronze should be fluxed with HANDY FLUX™ or Sure Flo Brazing Flux to assure a sound braze joint.

The level of phosphorous also changes the fluidity and ductility of the material. The greater the percentage of phosphorous in the filler metal the more fluid the material will be. While this alloy is widely used in the air conditioning and plumbing industries, it is not for use on ferrous or nickel based materials because the joint will become brittle and may fail.

A Silver-Free Alternative to SIL-FOS®

FOS-FLO® alloys have many of the same characteristics of the SIL-FOS® alloys, except that they are free from silver, which significantly reduces the price of the material. Alloy forms available include wire, preforms and powder.

Lucas-Milhaupt Europe, part of Handy & Harman group of companies, is a provider of Global Brazing Solutions with the very best level of technical support. We offer innovative filler metal products, precious and non- precious. Our brazing expertise and knowledge of the processes of our customers is our key differentiator. We serve global OEMs in HVAC/R, Automotive components, Construction tools and Electrical components. Our leadership in the production of brazing alloys in North America is undisputed since former Wolverine has joined Lucas group of companies in 2013. In Europe we have 70 years presence with LM Ribérac (former Protechno) specialized in Handy One cored wire technology, aluminum in particular, and fluxes; and with LM Gliwice (former Inmet) a foundry and mill in Poland specialized in silver and copper based brazing alloys in wires and strips.

LM Global Brazing Solutions is your complete source for filler metal products available in a large variety of engineered forms and alloys, for metallic pastes and for wet and dry fluxes; more importantly we offer superior technical service to assist OEM customers in reducing the total cost of their brazing process. This includes alloy selection, filler metal calculation, cooperation on form design, tests support and training at customer site. Our field based technical sales team covers all regions of the world in support of your plant wherever it is located.

Lucas-Milhaupt high reliability metal joining solutions meet the needs of the latest generation of HVAC/R systems and components We will welcome your visit on our stand to discuss latest evolutions in HVAC/R brazing applications and see our most innovative products for aluminum brazing and soldering as well as our silver and copper based brazing alloys in various forms.

Handy One aluminum products range offers the industry an innovative low-temperature solution to join common aluminum alloys and aluminum to copper. Typical benefits are :

If you are brazing copper components our range of standard SILFOSFORUS and FOS-FLO® alloys are available in various forms (wire, rod, ring, disc, washer, etc… ). These copper based filler metals are self-fluxing on copper by virtue of their phosphorous content. Because of their self-fluxing nature, you save time and money by eliminating the steps necessary to flux before brazing. The phosphorous content changes the fluidity and ductility of the material. The higher the % of phosphorous in the filler metal the higher the fluidity of the filler metal. While this family of alloys is widely used in air conditioning and plumbing applications it is not for use on ferrous or nickel based components because the joint would become brittle and may fail. FOS-FLO® alloys have many of the same characteristics of the SILFOSFORUS alloys, except that they are free from silver, which significantly reduces the price of the filler metal. Lucas-Milhaupt provides a solution to all your applications, needs, constraints and budgets!
